摘　　要：针对涤纶吸湿性、染色性差,容易积聚静电,易起毛等缺点,探讨50%涤纶与50%阳离子改性涤纶混纺纱采用阳离子染料染色性能,对混纺纱进行前处理、染色、还原清洗、柔软整理,测试了染色纱线回潮率、断裂强力、色差、色牢度。结果表明,染色后纱线回潮率在0.4%以下,断裂强度及变异系数均无明显下降,耐水洗及耐摩擦色牢度均达到4级以上,表明阳离子染料对改性涤纶具有较好的染色效果及染色牢度。Modified polyester can improve the hygroscopicity dyeing, easy to accumulate static electricity, easy to pilling and other shortcomings of polyester fiber. In this paper, the dyeing properties of 50% 21 tex terylene and 50% cationic modified polyester blended yarn were discussed, and the blended yarn was pretreated, dyed, reduced and cleaned, and softening, and the dyed yarn moisture regain, breaking strength, color difference, color fastness were tested. The results show that the moisture regain is less than 0.4%, the breaking strength and coefficient of variation are not significantly decreased, and the washing fastness and rubbing fastness reaches above grade 4 after dyeing. It indicates that the cationic dyes had a good dyeing effect and good color fastness on the modified polyester.
